It's been five generations after the first war between Samurai and Shinobi. The five villages were founded shortly after and there has never been a war between them. Until now, all five villages have been off limits to the outside world, however the gates have been opened and ninja were allowed to travel between. But suddenly, kage are falling ill and no one knows who's behind it. The Hokage and Raikage both lie in comatose state, awaiting an answer as to what put them there.

I believe it's to have a Canon Section with all the official real Naruto stuff in one area while the other made up clans are in made up crazy shiz world. I like library sections on sites, or canon sections, cause I for one don't like using custom clans and if I want one I can just go to the canon clan section, see all the stuff I'm familiar and comfortable with and pick one.
